In a typical optical link, data is first transferred from the electrical to the optical domain using an or a directly modulated laser. An electro-optic modulator can vary the intensity and/or the phase of the optical carrier. In silicon photonics, a common technique to achieve modulation is to vary the density of free charge carriers. Variations of electron and hole densities change the real and the imaginary part of the refractive index of silicon as described by the empirical equations of Soref and B.

Silicon photonics has developed into a mainstream technology driven by advances in optical communications. The current generation has led to a proliferation of integrated photonic devices from t.
Crystalline silicon is today's main photovoltaic technology, enabling to produce electricity with minimal carbon emissions and at an unprecedented low cost. Department of Energy (DOE) Solar Energy Technologies Office (SETO) supports crystalline silicon photovoltaic (PV) research and development efforts that lead to market-ready technologies. PV modules (also known as PV panels) are linked together to form an enormous array, called a PV array, to meet a specific voltage and current need. A PV module is a critical component in. NLR is working to increase cell efficiency and reduce manufacturing costs for the highest-efficiency photovoltaic (PV) devices involving single-crystal silicon and III-Vs. We develop new solar cell and module concepts for our customers, evaluate.
Bulk silicon carbide (SiC) has become an emerging high-performance waveguide material due to its optical properties, mechanical strength, and thermal stability, especially suitable for use in augmented reality (AR) glasses, which have strict optical display requirements. The exceptional virtues of SiC, such as an expansive bandgap, impressive thermal conductivity and unyielding covalent bonds usher it onto the pedestal in. SAN FRANCISCO, Jan. 23, 2026 /PRNewswire/ -- Goeroptics, a world's leading AR&MR solution provider, unveiled a suite of advanced XR optical solutions at SPIE AR|VR|MR 2026. The company debut its latest AR flagship product, the F50Se — a 50° FoV full-color silicon carbide (SiC) etched optical module. Optical-grade refinement of silicon carbide (SiC) from Meta is a landmark in the pursuit of a superior AR form factor. SiC Optics' ability to be shaped into various forms and its high specific stiffness make.

We demonstrate silicon nitride mode-division multiplexing (MDM) and wavelength-division multiplexing (WDM) using asymmetrical directional couplers and microring resonators. tial components in many applications, especially in optical communications. With this approach we have shown that stoichiometric and N-rich SiNx layers can. We design and experimentally demonstrate a four-channel cascaded Mach–Zehnder interferometer (MZI) with flat-passband for coarse wavelength division multiplexing, based on a silicon nitride platform. The performance of MZI filters is closely related to the design of power splitters.
